I need to convert a sub-string of a string with a character in javascript.

I used following code to do that

av_text_to_display = av_text_to_display.replace("a*^!", "'");

but it can only replace first occurrence. I used following code for all occurrences

av_text_to_display = av_text_to_display.replace("a*^!", "'", "g");

but it is not a standard way. What is the standard way to do that?

  • Read the [docs for `replace`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/replace), and then please use regex instead of string literals. – Bergi Oct 26 '15 at 15:35

You are searching with a string instead of a RegExp, it should probably be:

av_text_to_display.replace(/a*\^!/g, "'");

If you're trying to replace that literal string, and not a regex matching that string, use an escaped regex:

av_text_to_display = av_text_to_display.replace(/a\*\^!/g, "'");


var av_text_to_display = "here: a*^!, there: a*^! and also here, twice: a*^!a*^!";

av_text_to_display = av_text_to_display.replace(/a\*\^!/g, "'");

console.log(av_text_to_display);

If you don't want to use regex you can use the both split and join functions to do this :

your_string.split("a").join("'");

Hope this helps.
